[PATCH v1 1/1] bbdev: fix possible null pointer dereference

[Nicolas Chautru <nicolas.chautru@intel.com>]

This change addresses the CID 457446:  Null pointer dereferences
(REVERSE_INULL). Not expected to happen in practice, but the
config may be potentially undefined through API.

Coverity issue: 457446
Fixes: 61aa25b96e14 ("bbdev: add trace points")
